Geospatial correlation between COVID-19 health misinformation and poisoning with household cleaners in the Greater Boston Area.

INTRODUCTION: Calls to poison control about exposure to household cleaners have increased during the COVID-19 pandemic. This dynamic may reflect increased exposure from public health efforts as well as health misinformation shared on social media. METHODS: We analyzed the dynamics of calls to the Regional Center for Poison Control and Prevention serving Massachusetts and Rhode Island (MARI PCC) and tweets discussing treating COVID-19 with house cleaners from January 20, 2020 to May 5, 2020. We obtained publicly available tweets discussing the use of household cleaners to "cure COVID" from the same time period with geographic co-ordinates indicating that they were emitted from the Greater Boston Area. RESULTS: Our main finding is that public health efforts were followed by a sustained increase in calls after March 15, 2020 (10 ± 2 calls per day before to 15 ± 2.5 after) while misinformation on social media was associated with intermittent spikes in calls. Overall, calls significantly increased during the study period by 34% as compared to the previous 8 years, mostly reporting unintentional ingestions with no serious effects. The daily volume of tweets and retweets was significantly correlated with daily call rates to MARI PCC for the surrounding 7-10 days. CONCLUSIONS: Health misinformation on social media about using household cleaning agents to treat COVID-19 and public health efforts lead to different dynamics in PCC calls. Public health efforts were followed by a sustained increase in calls after March 15, 2020 while misinformation on social media was followed by intermittent spikes in calls. This analysis is the first to link the geospatial dynamics of social media and public health interventions to poison center calls about exposure to household cleaners.

Tracheal and bronchial obstruction following cyanoacrylate aspiration in a toddler.

INTRODUCTION: Cyanoacrylates are a common class of household substances used as adhesives and are commonly sold under brand names such as Super Glue, Krazy Glue, and others. We are reporting a case of accidental cyanoacrylate adhesive aspiration by a toddler complicated by tracheal and bronchial obstruction. CASE REPORT: A toddler ingested a low-viscosity cyanoacrylate product and developed a severe, persistent cough. Initial vital signs, oxygen saturation, lung sounds, and chest radiograph were unremarkable. Rigid bronchoscopy was performed and several pieces of glue were removed from both main stem bronchi. The child made a full recovery after a 10-day hospital stay. DISCUSSION: Cyanoacrylate ester polymers are hard, glassy resins that exhibit excellent adhesion to a variety of materials. Aspiration of these products is a poorly described clinical entity. CONCLUSION: The low viscosity of cyanoacrylate adhesive formulations makes aspiration of these products a rare but potentially life-threatening exposure. Management centers upon supportive care and consideration of rigid bronchoscopy for removal of adherent glue.
